Projection Screen Selection

ViewSonic Pro8100’s preset image modes are calibrated based on a no-gain, pure flat white projection screen. For best preset performance, it is highly recommended to use a no-gain, flat white professional projection screen. The projection screens used in most office are gain-screens. Material used in brightness gain screen will cause decrease in viewing angle and hot-spot symptom. Black level and contrast performances can also be altered by the gain-screen since the gain will also boost the dark level brightness. The so-called hi-contrast gray projection screen can also alter the contrast and black level performance. The best viewing performance can not be brought by the standard factory presets, when using these types of projection screens.

Please seek professional help for adapting a specialized screen, when calibrating the projector settings manually.

•Make sure all intake and exhaust ventilation are not blocked.

•Do not use the projector in a smoky environment. Smoke residue can cause buildup on critical parts.
